I-IYDRANT-REPAIRING TOOL.

To all whom it may concern Be it known that we, THOMAS L. Giunr andBURNICE N. L sBY, citizens, of the United States, residing atElizabethtown, in the county of Hardin and State of Kentucky, haveinvented certain new and useful Improvements in Hydrant-Repairing Tools,of which the following is a specification. v

Our invention relates to a tool for use in repairing hydrants, bygrinding the valve seats thereof.

An important object of the invention is to provide a tool of the abovementioned character which is simple in construction, inexpensive tomanufacture, convenient in use, and formed of few and simple parts whichmay be readily separated and assembled.

A further object ofthe invention is to provide a tool of the abovementioned character, having means for connecting the reamer directly tothe rotatable rod or to a coupling adapted to be secured to the rod andcarrying a guide sleeve, whereby the tool may be used in hydrants havingcasings of different diameters.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame, Figure 1 is a side elevation of all the elements included in ourtool, showing the same in a position to be assembled, Fig. 2 is acentral longitudinal sectional view through the elements assembled, and,Fig. 3 is a side elevation of the tool, showing it arranged within thehydrant casing in a position to engage with the valve seat of thehydrant.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of our invention, the numeral 5 designates arotatable rod or body portion, to the upper end of which is secured, asshown in Fig. 1, a handle 6 for turning it, while in Fig. 3 a crankbrace 7 is secured thereto. It is to be understood that any suitablemeans may be employed to turn the rod 5. Rotatably and longitudinallymovably mounted upon the rod 5 is a guide sleeve or cap 8, adapted tofit over the top of the hydrant casing 9, and carrying winged clampingbolts 10 to engage therewith, as shown.

\ Specification of Letters Patent. 2 7

Application filed March 2, 1915. Serial No. 11,617.

Patented Dec. 7, 191-5.

The forward or lower end of the rod 5 is provided with'a' screw-threadedportion 11, to the end of which is secured'the reduced screw-threadedportion or trunnion 12. I

The numeral 13 designates a coupling,

"having a tubular portion 1 1, internally screw-threaded for engagementwith the screw-threaded portion 11 and detachable therefrom. The reducedscrew-threaded portion or trunnion 12 is adapted to'extend within theopening of the tubular portion 14:, as shown. The coupling 13 isprovided at its forward end with an enlarged head 15, carrying'a flange16 and forwardly of this flange an enlarged screw-threaded portion 17,as shown. This screw-threaded portion carries a reduced screw-threadedportion or trunnion 1 8, as shown.

The numeral 19 designates a reamer, having a central screw-threadedopening to receive either of the screw-threaded extensions or trunnions12 and 18, having the same diameter. In Fig. 2, we have shown the reamer19 as arranged upon the screwthreaded trunnion 1S.

The numeral 20 designates a guide sleeve, provided near its rear endwith internal screw-threads 21, to engage with the screwthreads of theenlarged extension 17, as shown. The guide sleeve 20 has its rear endengaging the flange 16 and is provided internally with an annularshoulder 22 engaging with the edge of the reamer 19, as shown.

In the use of the tool, the guide casing or cap 8 is secured to theupper end of the casing 9, and the rod 5 moved downwardly within thecasing, bringing the guide sleeve 20 over and about a tubular valve seat23, vertically arranged within the lower end of the casing 9. The guidesleeve 20 fitting about the tubular valve 23 holds the reamer 19 uponthe upperend thereof, which is to be cut or ground. Upon rotating therod 5, it is obvious that the reamer will cut or grind the upper end ofthe valve seat. Instead of having the cutting surface of the reamerarranged horizontal the same may be inclined for grinding conical valveseats.

Then the tool is used in connection with small hydrants, the casings ofwhich are not large enough to receive the guide sleeve 20, I

screw-threaded trunnion 18. The coupling 13 is now removed from the rod5 and the reamer placed upon the trunnion12. The rod carrying the reamerdirectly secured thereon is now passed through the casing of the hydrantand placed in engagement with the valve seat to be ground, which iseffected by rotating the rod. If desired the rod 5 may be extensible andfor this purpose it may be formed in sections, connected by detachablecouplings.

It is to be understood that the form of our invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to Within the scope of the appended claims without departingfrom the spirit of the invention.

Having thus described the invention, we claim:

1. A tool of the character described, comprising a rod provided at itsforward end with screw-threads and a reduced screwthreaded trunnion, acoupling embodying a tubular portion internally screw threaded forengagement with the screw-threads of the rod and provided at its forwardend wlth a reduced screw-threaded trunnion, a guide member carried bythe coupling, and a reamer adapted for engagement with either of thescrew-threaded trunnions.

2. A tool of the character described, comprising a rod provided at itsforward end with screw-threads and a reduced screwthreaded trunnion, acoupling embodying a tubular portion internally screw-threaded forengagement with the screw threads of the rod and provided at its forwardend with a reduced screw-threaded trunnion, a guide sleeve havingscrew-threaded engagement with the forward end of the coupling andsurrounding the trunnion thereof, and a reamer adapted for engagementwith either of the screw-threaded trunnions.

In testimony whereof we aflix our signatures in presence of twowitnesses.
